Experimental: MEDI3414 [Influenza A (H1N1) vaccine]
MEDI3414 - Monovalent vaccine was supplied in intranasal sprayers containing a total volume of 0.5mL of sucrose-phosphate buffer, egg allantoic fluid, and approximately 10^7 fluorescent focus units (FFU) of live, attenuated influenza virus reassortant A/California/7/2009 strain that was propagated in chicken eggs.
H1N1 monovalent influenza vaccine (MEDI3414) contained no preservatives and no adjuvants.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Participants With Fever Post Dose 1 (Days 1-8), Defined as an Oral Temperature ≥ 101°F (38.3°C).
Time Frame: Days 1-8
|
The number of participants with fever between the two treatment groups was compared based on the upper limit of the two-sided 95% exact confidence intervals (CIs) for the rate difference (Vaccine minus Placebo).
The upper limit of the two-sided 95% CI was evaluated against the prespecified equivalence criterion of 10% which corresponded to the following hypotheses • H0 (null): rate difference ≥ 10% • HA (alternative): rate difference < 10%

|
Number of Participants Who Experienced a Post Dose 1 (Day 15) Seroresponse Against the H1N1 Strain in All Participants Regardless of Baseline Serostatus
Time Frame: Day 1, Day 15

Seroresponse was defined as a ≥ 4-fold rise in hemagglutination inhibition (HAI) titer from baseline.
All immunogenicity analyses were based on the immunogenicity population.
